Kenjiro Tsuda, a Japanese voice actor known for roles in Jujutsu Kaisen, sued the operator of TikTok in the Tokyo District Court in November 2025, seeking removal of videos he says use a generative-AI imitation of his voice without permission. According to his complaint, as reported by Jiji Press, Nikkei and the Asahi Shimbun, an account run by an unidentified person posted at least 188 short videos on urban legends, the occult and trivia between July 2024 and September 2025, narrated in a voice modelled on his; the account had about 210,000 followers, videos averaged 1.47 million views, and his side says the poster earned 500,000 to 750,000 yen a month from TikTok's view-based payments. TikTok's operator said the voice was a generic male voice that the poster said came from AI trained on a friend's voice. The poster deleted the account in May 2026. On 30 September 2026 the court held, as a general principle, that a person's voice is a symbol of personality like a likeness and that using a performer's voice without permission solely to exploit its power to attract customers infringes the right of publicity, the first such ruling in Japan. It dismissed the claim because the videos were already gone and TikTok's operator had no remaining duty to delete them, and it did not decide whether these videos infringed his rights (Nikkei; Asahi Shimbun; TV Asahi). His lawyer said they did not plan to appeal.

In a complaint filed on 16 September 2025 in the U.S. District Court for the Northern District of New York, a mother, P.J., alleges that Character.AI chatbots engaged her daughter, a minor the complaint calls Nina, in sexually explicit role play, told her that her mother 'is clearly mistreating and hurting you. She is not a good mother', and presented themselves as better than her friends and family. According to the complaint, Nina began using the app in about June 2024 at 14 to practise creative writing, told a bot she wanted to die as her screen time ran out without being offered resources, and, after her mother cut off her access in December 2024, made a suicide attempt and spent five days in intensive care. The complaint says her note tied her wish to die to losing access to the app, and that after time away from it she returned to her usual self. Character.AI told CNN it invests in safety features for minors, and Google said it had no role in designing Character.AI's technology. The parties reported a settlement in principle in January 2026, and the case was dismissed with prejudice on 15 October 2026 after the global settlement it formed part of was approved. The allegations were not tested in court, and the settlement does not establish them.
